# ARP Odyssey
“RP Odyssey with expression pedal and portamento foot switch. I bought this new in 1974.
Modified/upgraded with standard CV/gate/trig 1/8″ ins and outs. Later Odyssey’s had this as standard. Connects to other ARP gear with same. Also connects to external MIDI box (not included) for control from any MIDI keyboard.
Also modified to accept preamp’d audio input for processing by filter and ring modulator. Filter can sweep audio input via LFO, pedal, sample/hold.
Switch the toggle (near the pitch bend knob) from “VCF” to “RM” and the ring modulator compares the pitch of VCO2 to audio input and produces a third tone. VCO 2 pitch can be swept same as the filter for modulation FX. Great for those clangorous guitar tones ala Jeff Beck.
Mods were done in the 70′s by John Viera of (then) WAVES, in San Francisco.
XLR output added, no direct box required!
All parts functional, but needs some real TLC. Sliders and switches are noisy, keyboard action sloppy (see photo). VCOs could use calibration. Cosmetically OK, better than many other 35 year olds I know.” Link
